We're dividing 80420552 by 455 
Let's see how many times 455 fits into 80420552.

On to step 1:
455 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 455

Moving on to step 2:
455 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 455

Moving on to step 3:
455 goes into 804 1 times with a remainder of 349.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 455 away from 804, we end up with 349.
Grab the next digit (2) from the dividend, add it to 349, then carry on: 3492 / 455

Going ahead to step 4:
If we divide 3492 by 455, we get 7 and a remainder of 307.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 3185 from 3492 leaves us with 307.
Append the next digit (0) from the dividend to 307 and continue with: 3070 / 455

Step 5:
3070 divided by 455 is 6 with a remainder of 340.
Use 6 as the next digit of our solution. 
Result so far: 176.0
Deduct 2730 from 3070 and we're left with 340.
Append the next digit (5) from the dividend to 340 and continue with: 3405 / 455

Step 6:
When dividing 3405 by 455, we get 7 with a remainder of 220.
The number 7 becomes the next digit in our result. 
Result so far: 1767.0
Deduct 3185 from 3405 and we're left with 220.
Fetch the next digit (5) from the dividend, attach it to 220 and continue: 2205 / 455

Let's proceed to step 7:
If we divide 2205 by 455, we get 4 and a remainder of 385.
Write down 4 as next digit of the result. 
Result so far: 17674.0
Subtracting 1820 from 2205 leaves us with 385.
Fetch the next digit (2) from the dividend, attach it to 385 and continue: 3852 / 455

Moving on to step 8:
455 goes into 3852 8 times with a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 176748.0
If we take 3640 away from 3852, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 9:
If we divide 2120 by 455, we get 4 and a remainder of 300.
Use 4 as the next digit of our solution. 
Result so far: 176748.4
Deduct 1820 from 2120 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 10:
3000 divided by 455 is 6 with a remainder of 270.
The number 6 becomes the next digit in our result. 
Result so far: 176748.46
The remainder is 270 after subtracting 2730 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 11:
If we divide 2700 by 455, we get 5 and a remainder of 425.
The next digit of our result is 5. 
Result so far: 176748.465
If we subtract 2275 from 2700, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 12:
455 goes into 4250 9 times with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 176748.4659
Subtract 4095 from 4250 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 13:
455 goes into 1550 3 times with a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 176748.46593
If we subtract 1365 from 1550, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 14:
If we divide 1850 by 455, we get 4 and a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 176748.465934
If we take 1820 away from 1850, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
455 goes into 300 0 times with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 176748.465934
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 16:
When dividing 3000 by 455, we get 6 with a remainder of 270.
Record the quotient 6 as the next digit in the result. 
Result so far: 176748.46593406
If we take 2730 away from 3000, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

In conclusion, the division gives 176748.46593406 with a balance of 2.7e-07.
